Try one of this (depends wheter you need encrypted swap or not):

1. create zvol with 4k blocksize instead of default 8k:
     zfs create -b 4k -V 4g tank/swap
     swapon /dev/zvol/tank/swap

2. use geli encrypted swap with a sectorsize of 4k:
     zfs create -V 4g tank/swap
     geli onetime -s 4096 /dev/zvol/tank/swap
     swapon /dev/zvol/tank/swap.eli
